To all whom it may concern:

Be it known that I, OTTO J. GAsAU, a citizen of the United States, and aresident of Brooklyn, in the county of Kings and State of New York, haveinvented certain new and useful Improvements in Mattress Fabrics, ofwhich the following is a specification.

The invention pertains more particularly to mattress fabrics or springbed bottoms, and it consists in the novel features and structurehereinafter described, and particularly pointed out in the claims.

The mattress of my invention comprises a novel mattress fabric formed oftransverse sections suitably hooked together and preferably secured tousual head and foot bars by helicals and to side members by links. Oneobject of this inventionis to facilitate the manufacture and assemblingof the sections of a' wire mattress fabric and to provide sectionswhich, when assembled, will create a diamond effect throughout thefabric, the openings or meshes in, the fabric being of true diamondoutline and the de-- fining wires in the assembled fabric being eX-tended on substantially continuous straight crossing lines diagonally ofthe mattress.

1 form each transverse section of the mattress, by preference, from oneintegral rod of wire bent zigzag to define between eac.. two adjacentmembers thereof the outline of one-half of a diamond figure, and at theinner apex or junction point between each two adjacent members I form adoublestrand hook, while at the outer apex point between each twoadjacent members I form an eye. The eyes of one transverse section ofthe mattress fabric are adapted to be caught upon the hooks 0f the nextadj acent section of the mattress fabric and in this way the mattressmay be built up from the transverse sections with the least possibledelay. The formation of the transverse sections of the mattress is suchthat said sec tions may be readily and durably manufactured and, whenassembled, present a spring structure of uniform appearance and one inwhichstrains are equalized throughout the mattress in a manner tendingto render the mattress mechanically and otherwise of ad vantageouscharacter. 7

The invention will be fully understood from the detailed descriptionhereinafter Fig. 4 is an enlarged view, partly broken away, showing thedouble-hook end on one section of the mattress and illustrating bydotted linesthe connection of said hook with an eye on an adjacentsection of the mattress and the effect on the double-hook of a tensionplaced on the spring mattress, such tension acting to draw the adjacentside members of the hookin a direction toward each other, as the dottedlines indicate;

Fig. 5 is a top view, corresponding with Fig. 1, illustrating a modifiedconstruction ofdthe transverse sections of the mattress; an

Fig. 6 is a top view, partly broken away, of one of the transversesections of the mattress shown in Fig. 5.

The wire fabric is connected at its ends by helicals 10 to end rails 11and at its sides by links 12 with side members of suitable type 13 whoseends are connected by helicals 14 with the aforesaid end rails 11.

My invention pertains more particularly to the wire fabric, and thisfabric will be connected with the usual types of frames em ployed bymanufacturers of wire mattresses, these frames, as is well known,comprising rigid side bars and rigid end bars connected therewith andusually arranged on a higher tions 15, 16, all of the sections 15 beingalike and all of the sections 16 being alike, and the sections 15, 16being alike with the exception that at their outer side ends the wiresof the. sections 16 are formed into eyes 17 to receive the side ends ofthe sections 15 and the inner ends of the'links 12 by which the fabricmay be secured to the side or edge members 13.

Each section 15 is formed from a single rod of wire bent into zigzagform to define equal members sharply defining the shape of one-half of adiamond figure,'said halfdiamond shapes alternately extending inwardly,as at 18, and outwardly, as at 19, and said shapes 18, 19 being coequaland presenting straight though diverging equal edges or members 20, 20.At the outer apex ends of the mesh shapes 18,the wire of each section 15is bent to form eyes 21 which are preferably closed by twisting the wireat what would otherwise be the open side.

i of the eye, this closing of the eyes 21 serving to strengthen thefabric without adding material expense thereto; and at the inner apexends of each shape 19 of the sections 15 l bend the adjacent portions ofthe wire members 20 into a double-hook 22 which has parallel closelyrelated longitudinal sides 23 of such length as to admit, under strains,of a slight yielding of the same toward and from each other, asindicated by the dotted and full lines in Fig. 4. The side members 20 ofthe shapes 19 are brought into close relation to each other and thenbent longitudinally to form the hooks 22, said hooks when thus formedwith the said side members 20 brought nearly together serving as verydurable connecting means for the adjacent transverse section 16 of thefabric without destroying the true diamond effect I seek to maintainthroughout the entire extent of the fabric. The wire of each section 15at its side ends is formed into a hook 24 to engage the eyes 17 at theends of the next adjacent fabric section 16. Each transverse fabricsection 15 is thus of zigzag outline defining equal half-diamond spacesbetween the adjacent zigzag members thereof and each of said spaces atits outer apex end is formed with an eye 21 and at its inner end withthe double-hook 22, the eyes 21 being preferably closed by the twistingof the wire, as shown at the upper end of Fig. 1, and said hooks beingpreferably formed of closely related parallel side members which are, bypreference, slightly separated from each other.

The transverse sections 16 correspond substantially throughout with thesections 15,

with the exception that the zigzag portions of the sections 16 arereversed from those of the transverse sections 15 so that in matchingthe spaces of th sections 15, .16,

true diamond-shaped meshes are created. The outer apex ends of thezigzag members of the sections 16 are formed with eyes 21 1corresponding with the eyes 21 of the sections 15, and at their innerapex ends the members of the sections 16 are formed with thedouble-hooks 22 corresponding with the double-hooks 22 of the members ofthe sections 15. The eyes 21 of the members of the section 16 areengaged upon the hooks 22 of the members of the adjacent section 15, andthe double-hooks 22 of each section 16 are engaged by the eyes 21 of thenext adjacent transverse section 15, as will be clearly understood onreference to Fig. 1. The only difference between the sections 15, 16,with the exception of their reverse order, is that at its ends thesection 15 is formed with hooks 2t and the section 16 is formed at itsends with eyesl? to engage said hooks 24: and also receive the innerends of the links 12. The sections 15, 16 are therefore substantiallyalike in all essential respects, and in the finished fabric saidsections are arranged in reversed order so that the zigzag spaces of thesection 15 and the zigzag spaces of the section 16 may open into oneanother and form true diamond mesh outlines. The zigzag members of thesections 15, 16 are at equal angles, and hence when all of the sections15, 16 have been. connected together to form the mattress or springfabric, said members extend along substantially continuous crossingdiagonal lines, whereby strains exerted on the fabric are distributedalong said diagonal lines, which are substantially unbroken orcontinuous throughout the fabric. The eyes 21 extend outwardly beyondthe apexes of the zigzag shapes of the sections'15, 16 and are as smallas may be consistent with the ready assembling of the parts of thefabric, and the hooks 22 extend inwardly at the apex points of thesections 15, 16 alternating with the planes of said eyes and have theirsides brought as close together as may consistently be done so as to'increase the strength and resisting qualities of the fabric and preservethe diagonal formation of the lines defining the diamond-shaped meshesof the fabric. The side members 23 of the hooks 22 arepreferablyslightly separated so that in the event of strains on thefabric, said sides may, at their inner ends, yield with, V

the sides of the zigzag bends of the sections, thereby relieving thefabric of a rigidity it might otherwise have.

Figs. 5 and 6 illustrate a modification of manner shown in Figs. 1 and2. In other respects the construction shown in Figs. 5 and 6 is the sameas that presented in Figs.

i and 2, and therefore to avoid needless explanation I number Figs. 5and 6 with the same numbering employed on Figs. 1 and 2, with theexception that the eyes numbered 21 in Figs. 1 and 2 are, in Figs. 5 and6, numbered 30. The sections of the fabric shown in Figs. 5 and 6 definethe same diamond outlines presented in Fig. l and The fabric composed ofthe sections 1 5,

16 is of particular advantage in that said sections form independentelongated units and may be easily assembled to form a fab.- ric of notonly ornamental configuration, but one possessing substantiallycontinuous crossing diagonal lines capable of resisting strains and notliable to unduesagging. regard it as particularly important that thewire members of the assembledv units extend on substantially continuousdiagonal crossing lines creating the diamond-shaped meshes and lines ofresistance extending diagonally of the fabric in crossing directions andbeing substantially unbroken, so that the lines of resistance aresubstantially directly through the zigzag side members of the portionsof the respective units or sections of the fabric.
